Hello,
Is there a way to download Costco warehouse transaction history?
It sure does not look like it. But, you might contact Costco Customer Service and ask them.
In the website, it you go to “Orders & Returns” and then click to “In-Warehouse” it shows each of your visits, with date, time, location and cost. Clicking on “View Receipt” allows you to download an itemized receipt. This isn’t something that could easily be imported into Tiller, but it does provide all the information if you’re willing to spend the time processing it…
/r/Costco/comments/10r0thr/download_purchase_history someone posted here that costco can provide a pdf report, would need to import to excel
Can you clarify here 
@twobrain ?
Someone commented that if you contact Costco customer service, Costco will send you an itemized transaction history.
Nice tip, thanks for sharing!
just learned about costco pdfs parsing into csv with the following tool. GitHub - GonzaloZiadi/CostcoWrapped: Parse your Costco receipts
sounds the amazon import tool could be modified to allow for costco csv to be imported.
maybe there could be some sort of ai agent that could automate some of this, idk.
just thinking about how to separate out groceries from costco transactions.
resurfacing this thread, since this should be pretty easy now with the following instructions. Reddit - The heart of the internet
the script allows you to export your line items in a json probably very similar to the amazon export. not sure how to make a community plug in to import the costco export though. could probably throw it into AI to mimic the format of the amazon output and utilize th existing amazon plugin
This is a pretty old thread, but it’s not that hard to get the costco receipt into CSV format.
All you have to do it open the receipt in the website, and the copy and paste it to excel or google. Don’t paste values, but do keep the formatting. You’ll get the three columns. you might have to have a few helper columns to actually get it into the right format, but that’s not that difficult. With a small amount of work you could get it into your Tiller sheet.
